Exact neural mass model for synaptic-based working memory

Dependence of the power on the number of loaded items.
Power in the θ-band (3-11 Hz) (A), in the β-band (11-25 Hz) (B) and in the γ-band (25-100 Hz) (C) as a function of the number NL = NI ≤ 5 of loaded items. The integral of the power spectra in the specified frequency bands are displayed for the mean membrane potential v1(t) of the excitatory population one (blue symbols), the mean membrane potential v0(t) of the inhibitory population (orange symbols) and the mean membrane potentials averaged over all the excitatory populations (green symbols). The power spectra have been evaluated over a 10 s time window, after the loading of NI items, when these items were juggling in WM. Parameter values as in Fig 8.
